SPECIFICATION forming part of Letters Patent No. 718,813, dated January20, 1903. Application filed March 21, 1902. Serial No. 99,282- (Nomodel.)

To ttlZ whom, it may concern.-

Be it known that I, LOUIS BERNHARD BA- RON, a citizen of the UnitedStates of America, residing at London, England, have invented a certainnew and useful Improved Cigarette- Making Machine, of which thefollowing is a specification.

In what are known as cigarette-making machines it has heretofore beencommon to comb out the tobacco and supply it to an endless travelingbelt, over which has been a traveling pressure-belt which formed the topof the channel and kept the tobacco down and assisted in conducting itto and through the compression-rollers, after passing through which thetobacco met the wrapping-paper usually traveling forward with a secondendless belt, the paper being pasted at the edge and wrapped around thetobacco and the continuous cigarette-rod passed out through cuttingmechanism which cuts the same into predetermined lengths.

The present invention relates to. improvements in machines for forming acompressed continuous rod of tobacco and maintaining it in itscompressed form while the paper is being wrapped and pasted about it inthe usual manner.

In the accompanying drawings, Figure 1 is a side elevation of a completemachine embodying many known features as well as those of the presentinvention, the remaining figures of the drawings being on a largerscale. Fig. 2 is a sectional elevation on the line 'A of Fig. 3, showingthe combing mechanism and delivery-chamber to the first traveling belt.Fig. 3 is a side elevation, partly in section, of the compressingmechanism. Fig. 4 is a plan view of Fig. 3 with the verticalcompressing-wheels removed. Fig. 5 is an elevation on line B of Fig. 3.Fig. 6 is an elevation of part of the mechanism shown in Fig. 5, but ona larger scale. Fig. 7 is an elevation on line C of Fig. 3, also on alarger scale. Fig. 8 is an elevation on line D of Fig. 3, also on alarger scale. Fig. 9 is a side view of the plate or trough-cover betweenthe first vertical and the horizontal compressing-wheels. Fig. 10 is aview of the same from beneath. Fig. 11 is a side view of the secondplate or trough-cover between the horizontal and the second verticalcompressing-wheels. Fig. 12

is a view of the same from beneath. Fig. 13 is a side elevation incontinuation of Fig. 3. Fig. 14 is a plan view of same; and Figs. 15,16, and 17 are cross sections, on a larger scale, on lines E, F, and G,respectively.

. According to this invention the tobacco passes through the feed andcomb cylinders 1 and down the closed discharge-chamber 2 to the feedtrough 3, the bottom of which is formed of the first endless belt/l,which travels over the base-plate 5. The inner faces of the trough 3close to the first compressionwheel 6 are curved inwardly from thesides, so as to fit closely to wheel 6, the result being that as thetobacco passes under the wheel it is subjected to substantial topcompression, as well as slight side compression, as will be clearlyunderstood by reference to Figs. 4, 5,

and 6. The partially compressed and formed rod of tobacco is taken fromwheel 6 by trough plate or cover 7, which is provided with adownwardly-inclined opening 8, (most clearly seen in Figs. 7 and 10,)and, rearwardly a projecting piece 9, adapted to fit closely to thehorizontal compression-rollers 10, the peripheries of which are incontact top and bottom, while the curved space between at the point ofcontact has the same cross-section as the shape of the tobacco rod it isdesired to produce. This construction causes the tobacco to be firstpartially compressed vertically and then to be passed beneath adownwardly-inclined cover-plate, which causes further verticalcompression and conducts the verticallycompressed rod to be deliveredbetween the horizontal compression-wheels 10, which being in absolutecontact above the groove formed between them prevent any relaxation ofthe vertical pressure, while themselves impartingthe horizontalpressure'necessary to complete the rod.

The tobacco rod is prevented from clinging to rolls 10 byclearing-fingers 11, (see Fig. 3,) which may be attached to theframework or to second cover-plate l2, fitting close to rollers 10 andprovided with a slightly-enlarged mouth, so as to slightly relieve thepressure as the tobacco rod is passing from the first endlessband 4 ontothe paper 13, which is carried on the second endless band 14:, thetobacco rod being immediately recompressed and formed to its propershape by the second vertical pressurewheel 15, from which it passesunder the adjustable clearing and paper-curling tongue 16, which is mostclearly seen in Figs. 3 and S. This provision of an enlarged mouth oropening between the coverplate 12 and the trough and at the rear of saidplate, which is the exact opposite of the usual construction, is one ofthe special features of my machine. After the tobacco rod has beenstrongly compressed in a horizontal direction by the wheels 10 the sidesof said rod are apt to be much more compressed than the center. Theedges of the rod are thus likely to be matted together, while thecentral part is comparatively loose, and if this is not corrected thecigarettes made will not burn evenly. By allowing the rod to partiallyexpand, and it will do this if the space behind the wheels 10 is greatenough, this unequal compression corrects itself, so that whensubsequently recom pressed after it is placed upon the traveling band ofpaper the rod is of very nearly the same density throughoutits width.

It will be noted that the bed-plate 17is recessed, so that withpressure-wheel 15, papercurling tongue 16, and trough-cover 18 thetobacco rod is held in its proper shape while the paper 13 is wrappedaround it, pasted at the edge by mechanism 20, and again turned down andpressed thereon, as will clearly be understood by reference to Figs. 13to 17. The wrapping of the paper, pasting its edge, and the cutting ofthe rod by means of cutting mechanism (indicated at 19, Fig. 1) beingeffected in the known manner need not be further described.

The requisite motion of the various parts may be effected from a main driving-shaft 21, operating'in conjunction with the necessarycounter-shafts and gear, as will be readily understood.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a cigarette-machine, the combination of a pressure-wheel adaptedto partially compress the loose tobacco, a trough plate or cover adaptedto take the tobacco from said wheel said plate having guide-surfaces forfu rther reducing the bulk of the tobacco vertically and for guidingsame forward and a pair of horizontal compression-wheels for thehorizontal compression of the tobacco each wheel having a peripherywhich has a cylindrical upper part and a grooved lower part theperipheries of said wheels being in contact.

2. In a cigarette-machine, the combination of apressure-wheel adapted topartially compress the loose tobacco, a trough plate or cover adapted totake the tobacco from said wheel said plate having guide-surfaces for further reducing the bulk of the tobacco vertically and for guiding sameforward and a pair of horizontal compression-wheels for the horizontalcompression of the tobacco each wheel having a periphery which has acylindrical upper part and a grooved lower part the peripheries of saidwheels being in contact, a second plate or cover which permits thecompressed tobacco to expand slightly as it passes onto thewrapping-paper and a final compression-wheel adapted to finally compressand feed forward the tobacco rod.
